Description
FastFileCheck is a high-performance, multithreaded file integrity checker for Linux. Designed for speed and efficiency, it utilizes parallel processing and a lightweight database to quickly hash and verify large volumes of files, ensuring their integrity over time.

Goals
- Release v1.0.0
Design overwiew:
- Main thread (producer): traverses directories and feeds the queue (one thread is more than enough for most use cases)
- Dedicated consumer thread: manages queue and distributes work to threadpool
- Worker threads: compute hashes in parallel
This separation of concerns is efficient because:
- Directory traversal is I/O bound and works well in a single thread
- Queue management is centralized, preventing race conditions
- Hash computation is CPU-intensive and properly parallelized

Port OTPClient to GTK >= 4.18 by pstivanin
Project Description
OTPClient is currently using GTK3 and cannot easily be ported to GTK4. Since GTK4 came out, there have been quite some big changes. Also, there are now some new deprecation that will take effect with GTK5 (and are active starting from 4.10 as warnings), so I need to think ahead and port OTPClient without using any of those deprecated features.
Goal for this Hackweek
- fix the last 3 opened issues (https://github.com/paolostivanin/OTPClient/issues/402, https://github.com/paolostivanin/OTPClient/issues/404, https://github.com/paolostivanin/OTPClient/issues/406) and release a new version
- continue the rewrite from where we left last year
- if possible, finally close this 6 years old issue: https://github.com/paolostivanin/OTPClient/issues/123
pudc - A PID 1 process that barks to the internet by mssola
Description
As a fun exercise in order to dig deeper into the Linux kernel, its interfaces, the RISC-V architecture, and all the dragons in between; I'm building a blog site cooked like this:
- The backend is written in a mixture of C and RISC-V assembly.
- The backend is actually PID1 (for real, not within a container).
- We poll and parse incoming HTTP requests ourselves.
- The frontend is a mere HTML page with htmx.
The project is meant to be Linux-specific, so I'm going to use io_uring, pidfs, namespaces, and Linux-specific features in order to drive all of this.
I'm open for suggestions and so on, but this is meant to be a solo project, as this is more of a learning exercise for me than anything else.
Goals
- Have a better understanding of different Linux features from user space down to the kernel internals.
- Most importantly: have fun.
